[Libguestfs] [PATCH] Fix debug help error message

When given an invalid debug command, libguestfs responds with the error message: libguestfs: error: debug: use 'debug help' to list the supported commands However this command does not work, as debug requires 2 arguments. This change updates the message to prompt the user to use 'debug help 0'. --- daemon/debug.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-)
